OK, I am now running everything once w/o threads so it is fine for me, but
I added it back in.

Also, I see there are a lot of cached handles in aijcusparse.cu. If they
get set w/o threads (thread 0) and then get used later  in OMP that could
be a problem. My code runs fine and it first runs without threads and then
runs with 10 threads/solves using cuSparse ILU solves. So it seems OK.
